DESCRIPTION
The FPD48084 Column Driver is a direct drive, 256
gray level, 384 output, TFT-LCD column driver. This
device is ideally suited for LCD TV applications,
supporting WXGA resolution. It provides the
capability to display 16,772,26 colors (24-bit color)
with a large dynamic output range for wide viewing
angle technologies. This scheme supports digital
independent gamma from the TCON, and minimizes
required trace routing and PCB size.
The FPD48084 uses TI’s PPDS™ interface (Point to
Point Differential Signaling) to reduce wire count,
increase driving distance, enable advanced features,
and lower overall system cost. Coupled with an
FPD8020x timing controller, the FPD48084 is capable
of providing independent color for each of the three
subpixel colors (red, green, and blue), enabling the
color temperature and balance control that is needed
to provide cinema quality video performance for
advanced LCD TV applications.
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
